Captain Rudolf Seebass and flight officer Daniel Rieter commanded the flight and said it was a totally normal revenue flight. Passengers were informed once onboard that biofuel would be used and were given explanatory brochures. “They applauded when the announcement was made,” Seebass said.

Through its burnFAIR project, LH was the first airline to use biofuel on regularly scheduled commercial flights in an effort to study the long-term effect of biofuel on engine maintenance and engine life, as well as the environmental impact.

From July 15 to Dec. 27, 2011, a LH Airbus A321 operating on the Hamburg-FRA route had one engine powered by a 50-50 blend of regular fuel and biosynthetic kerosene. In all, 1,187 biofuel flights were conducted and, according to initial calculations, total consumption of the biokerosene mix amounted to 1,556 tons and CO2 emissions were reduced by 1,471 tons.

“This is the best news we could give the industry because it shows that we really can do normal operations with biofuel,” said LH VP-Aviation Biofuel Joachim Buse.

He said the transatlantic flight was particularly important because if LH could use biofuels on all US flights, it estimates it could reduce CO2 emissions by about 15,000 tons per week. The airline operates around 400 weekly flights to17 US cities.

The biofuel mix used by LH is mostly based on Camelina oil from the US with some Jatropha-based oil from Brazil and some animal fat from Finland.
